Kronik Pankreatitin Etiyopatogenezi ve Etiyolojisi
Özet
Kronik pankreatit; karın ağrısı, ekzokrin ve endokrin yetmezlik ile karakterize, pankreasta kalıcı yapısal hasara yol açan kronik inflamatuar bir süreçtir. Hastalık sıklıkla akut atakların devamı niteliğinde gelişmekte olup, dünya genelindeki en yaygın nedeni %45'lik oranla alkol tüketimidir; sigara ise bu süreçte doza bağımlı ve sinerjik bir risk faktörü olarak öne çıkmaktadır. Etiyolojik sınıflandırmada "TIGAR-O" sistemi (toksik-metabolik, idiyopatik, genetik, otoimmün, tekrarlayan/şiddetli akut pankreatit ve obstrüktif) kullanılırken, hipertrigliseridemi ve genetik mutasyonlar (PRSS1, SPINK1) da önemli roller oynamaktadır. Patogenezde asiner, adacık ve duktal hücre kaybı ile birlikte ilerleyici fibrozis görülmekte; bu durum zamanla diyabet, steatore ve malignite riskine zemin hazırlamaktadır. Erken evrelerde semptomlar epizodik ağrı ile sınırlı kalabilirken, ileri evrelerde kalsifikasyonlar ve kalıcı fonksiyon kayıpları belirginleşir. Tanı sürecinde hastanın tıbbi öyküsü, alkol/sigara kullanımı, genetik yatkınlığı ve serum IgG4 veya trigliserit düzeyleri gibi laboratuvar verileri titizlikle değerlendirilmelidir.
Chronic pancreatitis is a chronic inflammatory process characterized by abdominal pain, exocrine and endocrine insufficiency, leading to permanent structural damage in the pancreas. The disease often develops as a continuum of acute attacks, with alcohol consumption being the most common cause worldwide at a rate of 45%; meanwhile, smoking stands out as a dose-dependent and synergistic risk factor in this process. While the "TIGAR-O" system (toxic-metabolic, idiopathic, genetic, autoimmune, recurrent/severe acute pancreatitis, and obstructive) is used for etiological classification, hypertriglyceridemia and genetic mutations (PRSS1, SPINK1) also play significant roles. Pathogenesis involves the loss of acinar, islet, and ductal cells along with progressive fibrosis; this condition paves the way for diabetes, steatorrhea, and malignancy risk over time. In the early stages, symptoms may be limited to episodic pain, whereas in advanced stages, calcifications and permanent functional losses become prominent. During the diagnostic process, the patient's medical history, alcohol/tobacco use, genetic predisposition, and laboratory data such as serum IgG4 or triglyceride levels must be rigorously evaluated.
